Mathematics is often portrayed as an "abstract" cerebral subject, beyond the reach of many. In response, research with digital technology has led to innovative design in which mathematics can be experienced much like everyday phenomena. This lecture examines how careful design can "phenomenalize" mathematics and support not only engagement but also focus on key ideas. It argues that mathematical knowledge gained in this way prioritizes the powerful reasons for doing mathematics, imbuing it with a sort of utility and offering learners hooks on which they can gradually develop fluency and connected understanding.

Dave Pratt illustrates this lecture with examples taken from conventional topics such as number, algebra, geometry and statistics and from novel situations where mathematical methods are juxtaposed with social values. The suggestion that prioritizing utility supports a more natural way of learning mathematics emerges directly from constructionist pedagogy and inferentialist philosophy.
